--------------------------
[~dongjoon] Thank you for helping me review this issue!
I tried using version [Spark 4.1.0-preview2, Orc 2.2.0], but the problem still
persists.
And I compared these two versions of Orc, and the code processing logic here is
consistent between version 2.2.0 and version 1.7.8
As shown in the picture, this is my debug details
